5 INTRODUCTION This is no ordinary theater! Fasten your seat belt...it s a ride! The LEADER HOLLYWOOD FORMAT Stellar Mega Cinema (tm) Theater recently completed on Maui Hawaii during May and June 2016 is a Proof of Performance high performance theater. Created as a test bed, the final version will be integrated into a room of 1550 sq ft (144 Sq Meters) scheduled for completion during Q2of The final theater / screening room / studio will have a volume of 31,000 cu ft (878 Cu Meters). Variable room acoustics will provide for reverberation times to almost 1.5 seconds in addition to establishing both highly damped (echo and reflection free areas) and diffuse acoustical areas where a wide spacious unrestricted ambiance may be created. The final cinema system in 2018 will feature a CinemaScope curved screen width of 29 feet (8839 mm) x 12 feet in height (3658 mm). Peak Screen Illumination: 45 Fl. The system is designed to professional studio standards to include High Definition HDTV standards to include ATSC 3.0 (4K) and later to incorporate Digital Cinema Standards in full DCI compliance for HDR and HFR 4K and emerging 8K studio standards. The 2017/18 version of LEADER HOLLYWOOD FORMAT(tm) sound will feature a larger Main Screen Array than the test bed LHF certified system to include DOLBY ATMOS (tm) studio professional standard 3D sound with Very Large Format Leader LHF Custom Main Screen Channels to include large format Side and Rear surround arrays. In short, this Maui retreat set in 40 acres of the pristine Maui tropical paradise will serve as a producers inner sanctum sanctorum where all musical art forms to include Bach and Wagnerian masterpieces to Elvis and the Beatles to Kanye West with Country and Pop not to forget Opera and Hip Hop will dominate the music elements. Productions created for both TV and the cinema screen will have the capabilities of being screened and created as an extension of any and all studio facilities across the globe. As productions are bring viewed on ever decreasing screen size such as smart phones, ipads and tablets, giant screen cinema to include IMAX(tm) and competitors such as China s D-MAX in the GS market have ever increasing requirements in the technical requirements for superlative picture and sound. The LHF Stellar Mega Media(tm) studio and production theater has been designed and super scaled to meet the demands well into the next decade and beyond. THE MAUI TEST BED May & June 2016 In a word... wow does not cut it. Astonishing...getting closer. This is a R-I-D-E! better... Priceless wonderment... one of a kind... extraordinary... Zero to infinity in a blink! Then... one visitor exclaimed... This is beyond the Tesla Zone! Welcome to the LHF(tm) Stellar Mega Media Zone. Created for an international entertainment industry executive, Maui is the secret destination for producers such as Bob Rock ( Mötley Crüe, Bon Jovi, Bryan Adams, Metallica, David Lee Roth...), Oprah, Willie Nelson, Clint Eastwood, Shep Gordon,

6 Kris Kristofferson... Studio facilities tucked away provide world class levels of perfection on the world s most prized island travel destination (Conde Nast). Leader has provided studio recording studio equipment to Bob Rock s studio and now has completed our fourth advanced project on Maui, our first being the Leader LHF Ziggy Stardust project for David Bowie s organization ISOLAR and Manager Bruce Dunbar s waterfront residence. This project was featured in the December 2000 issue of Architectural Digest together with coverage on ABC s ET Entertainment Tonight. Engineering Prototypes are not all that photogenic. However, the concealed Hollywood insider studio secrets separates this radical expression of wonderment from the mainstay of both the AV (audio visual) and home consumer / home theater industry. While this system is short on interior design, the intent is to objectively measure dynamic performance levels and the on going aspects of Visual and Auditory Perception.

9 Close up view of the Lower Main Power Distribution Panel and Upper Breaker Panel for Rack B. The importance for clean stable power and the critical elements for Technical Isolated Ground is critical in extremely hi performance systems. The noise floor at full levels of operation in the absence of any audio signal, such as mute stop or pause, the noise floor must be inaudible completely devoid of any artifacts of hum or buzz. Power and grounding forms the basis of high performance.

10 Rear View of Power Distribution Unit A few connectors illustrated alongside a CD as a size reference OK...not the most glamorous images. However, consider the foundation of a stately building or a skyscraper. Without a solid foundation, well you get the point we are sure. The same holds true for high performance ultra low noise and high resolution sound systems...that being the foundation for clean stable power and low impedance grounding systems insures that unwanted artifacts such as power line noise, hum, annoying buzz, and interference is eliminated from the system. This is serious power...it s professional and we provide a CD as a visual reference to place the connectors in some perspective.

Full system calibration is dedicated to this source where full system equalization and overall balance between main channels and surrounds maintains the levels established during set up, test/calibration and rehearsal. Large scale mixing consoles may feed Matrix Input 2 or 3. Again, completely independent of the complexities required for Matrix 1 and critical balance for Motion Pictures, the mixing console feeds the main sound system simultaneously with Matrix 1. System balance and equalization is applied to Matrix 2 input again fully independently of those parameters set for other Matrix inputs. In this manner, live music, announcers, B Roll materials and return satellite feeds may feed the entire sound system including the surrounds in real time. 7

18 Mission critical reliability is afforded through the engineering and design process where Leader has created systems for The Walt Disney Company, NBC Television Network New York, Boeing Aircraft Company, General Motors, Phillips Collection Washington DC, National Symphony Orchestra, Canadian Broadcasting Corporation...where Mission Critical up time better than 100% is required. Illustrated above, professional XLR studio grade connectors in addition to the entire system calibrated to international studio operating levels insures accurate exchange of signals between input to output and to interstage devices along the way. 8

20 Technical LHF(tm) Data DRAFT DOCUMENT Designed to embrace all future systems and technologies to emerge over the course of the next 10 years, this Leader Hollywood Format(tm) system including 3Dx(tm) features designs to include future 8K professional formats. Emerging HDR (High Dynamic Range), HFR (High Frame Rate), laser projection to include sound systems beyond Dolby ATMOS(tm) and Auro 3D(tm) while embracing further enhancements to include Spherical Harmonic processes to further enhance the multi-dimensional aspects of optimizing 3D sound will establish the pinnacle of performance beyond the next decade. LHF(tm) benefits: unrivalled audience emotions and experiences. Similar to the world s most highly developed destination theater process known as Showscan(tm) this mega sized screen system based on 70mm film running at 60 FPS created images of such fluidity in motion, purity, color depth and brightness that to this day still out performs any IMAX(tm) theater or cinema process. The enormity of the LHF(tm) sound system enables full live performance of all contemporary musical forms to be performed to the highest standards. While peak cinema sound levels may extend to 115 db SPL, with average levels in the range of 85 to 100 db, live music necessitates systems with the ability to maintain an average level in excess of 118 db SPL in addition to providing headroom of 10 db. This results in peak levels approaching 128 db SPL at 10 feet. To insure mission critical reliability and complete system operation under demanding levels, the LHF Main Sound system as itemized below assures superlative levels of hi-fidelity across all musical genres from Wagnerian masterpieces to chamber orchestras, the whisper of a cello to the driving force of a Kanye West s best album of the decade My Beautiful Dark Twisted Fantasy or Dr. Dre s Nuthin But a G Thang. Simply turn it up up up and boogie baby! This current installation is truly unique on a grand scale on an international basis. Contained in a temporary 5000 sq ft / 465sq meters building this test Proof of Performance theater at 505 sq ft / 47 Sq Meters out performs any Giant Screen System in the world to include competitors such as China s D- MAX, IMAX(tm), IWERKS, MEGASYSTEMS, KINOTON, BOARDPERFECT, BALLANTYNE, and ADVANCED IMAGE SYSTEMS (AIS). The principle residence is to be completed toward the end of 2017 or early 2018, at which time this major system will be relocated into an approximate 1500 sq ft / 140 sq meters studio / theater presentation space. Prototype LHF(tm) screen channels were previously in use by REAL-D(tm) the world leader in cinema 3D imaging and projection. Installed in the Aidikoff / Leader Screening Room in Beverly Hills, this system has been applied in numerous Oscar(tm) For Your Consideration Screenings by The Academy of Motion Picture Arts and Sciences to include screenings by: Universal Pictures, Paramount, Disney, New Line Cinema, SONY Pictures, 20 th Century Fox, Warner Bros. REAL-D s developments were further enhanced through the application of Leader s 3Dx(tm) surround channels which provided a deeper and wider field in the surrounds to further enhance the 3D audience experience. 10

This major system will comprise the entire surround array. It is of staggering proportions. However, when completed, the Surround Channel power bandwidth will match the requirements for all 3D sound systems such as Dolby ATMOS(r) and Auro3D. Both completing 3D sound systems provide far greater frequency extension down to a level similar to the main screen channels. Public cinemas so equipped feature large format Sub Woofers located at the rear of the theater. This concept was first applied by Leader Cinema prior to all others in the industry commencing in Surround Array Speaker Systems (June 3, 2016) 2 each Leader 1503-xx-27 SD: Each Channel 2 x 15 / 1 x 12 / 1 x 9040 Wave Guide & Driver / Active Tri-amplified 2700 Watts Average (RMS) (Total L&R = 5400 Watts) Speaker Enclosures Total Weight both channels: 1680 Lbs / 764 Kgs 1 each Leader LHF jr SD 18 inch low frequency system (applied in the Surround Channel LF extension) 11

(Dolby ATMOS and Auro 3D provide for full low frequency extension. Installations in large scale cinemas include hi-power sub-woofer speaker systems mounted at the rear of a cinema). PHASE 2 (Estimated Q3 2017) LHF(tm) Features: Sound System as per above, with the addition of 22 side and ceiling position speaker systems to support 3D sound Boundary Layer wall system with variable acoustics within the studio / presentation theater Dolby ATMOS (professional) with Leader 3Dx(tm) 4K Digital Cinema DCI Compliant 3D image processing: TBA HDR + HFR Licenses (8K ready) Laser Projection: typical of Christie, Barco, NEC DCI Compliant Screen Size Curved (TBA) approx 24 ft W x 10 ft H ( 7.3 meters W x 3.0 meters H) PRIME Seating: 1.5 to 2H CinemaScope Angle of view at: 1H=10 ft 100 H x 54 V, 1.5H 78 H x 36 V, 2H 61 H x 29 V 8K will allow for seating as close as.8h or 8 feet.

24 Configuration for LFE Channel: 3 D SD combine to create the LFE channel below 100 Hz. Total amplifier power = 9600 watts average Six (6) each 18 special drivers. DXMS-24 processing routes the LFE signal to each of the combined L-C-R enclosures with dedicated equalization to optimize the LFE channels three (3) enclosures independent of a dedicated D1800 enclosure assigned to a Screen Channel for which a Screen Channels VLF and LF content is separately equalized and timed. Peak SPL capabilities in 1Pi or ¼ Space measured at 10 feet: 143 db SPL between 25 to 90 Hz In practice, the system is not operated to this level, however at 143 db SPL, this lies just under X Max, therefore safe thermal operation is assured. In cinema mode, the LFE Channel is calibrated and limited to a potential 122 db SPL (25 to 90 Hz) at 10 feet. Again, this is thermally safe to 125 db SPL, where given a typical duty cycle of LF and VLF content in Cinema, Power compression over 2 minutes is 0 db. In all practical applications, cinema applications typically calibrated to 85dB SPL at DOLBY 7 absolute peak energy may reach to 115 db SPL in the LFE, or incorrectly named sub woofer channel. Overall LFE channel weight 3 x D1800 enclosures: 1800 Lbs / 818 Kgs Similar system installed at the Leader-Aidikoff Screening Room in Beverly Hills California. System uses an additional three (3) SD enclosures and amplifiers in this room of 1500 Sq Feet / 140 Sq Meters. While motion picture sound tracks performed to specification utilizing three (3) 1800 systems, when dealing with the music industry, R&B and Rap artists their needs by far are considerably more demanding in extended power requirements for deep controlled bass. It should be noted, that, while this might appear to be excessive to many readers, the number of 2 enclosures containing a total of 4 x 18 inch systems designed to operate down to 20 Hz in quite common in major studios. An ideal example is Princes Paisley Park Studio in Minneapolis where each channel is supported with four (4) 18 inch devices in two enclosures. In a 2 channel Left Right configuration there is a total of eight (8) x 18 inch woofers...the results in an approx 700 Sq Ft / 65 Sq Meters control room is simply remarkable. All systems are soffit mounted. 14

VLF and LF Low Frequency System for Music Playback and Screen Channels (single D1800 enclosure) 1 D SD enclosure (three in total) operating in a 2 Pi boundary layer wall, with the enclosure loaded in 1 Pi or ¼ Space Typical large scale motion picture sound systems begin to roll off below 40 Hz, even though the LF enclosures typically contain dual 15 inch woofers. However, there is almost a full octave of information contained in a Screen Channel that is missing or considerable reduced in level when reproduced on the majority of sound systems installed throughout the world in public cinemas. In other words, a Screen Channel is bass shy. The Academy of Motion Picture Arts and Sciences 1100 seat Samuel Goldwyn Theater located in Beverly Hills California equalizes each of their five screen channels LF systems to be flat to 31.5 Hz. This establishes the desire among professionals to provide a more enjoyable movie experience with content contained in a Screen Channel. However, the LF systems at the Goldwyn in a dedicated Screen Channel are only 15 inch woofers, with four (4) transducers per enclosure. With such a large room, the screens LF enclosure is limited in both headroom and the ability to even reach further down in frequencies to 25 Hz. Yes, there is information below 30 Hz in a Screen Channel. The Leader D1800 as applied in a Screen Channel provides full power bandwidth down to 26 Hz independent of the LFE effects channel. The enhancement in music across all genres from classical to jazz to pop to heavy metal to hip hop and beyond becomes an experience impossible to recreate in any cinema. Further, special effects have a deeper more enveloping sense from the screen channels. 15

This includes chamber orchestras with delicate cello passages, full 9 foot grand pianos with bass performance output to the lowest note on a piano, Key No. 1 or A0 is 27.5 Hz to double basses in an orchestral setting or traditional jazz ensembles. Big band and Broadway Musicals together with dramatic Hollywood Motion Picture Scores to the drive of disco, hip hop to satisfy the likes of Kanye West or a Dr. Dre is the crowning achievement of any sound system. From Beethoven, Wagner and Chopin to Spryo Gyra to Jay Z...this system has it all. While there is much discussion in extending the low frequency performance to 15 Hz and lower, which is completely possible, research by Leader Acoustic Labs shows that far too many sound recordings and some motion picture sound tracks contain undesirable noise and air-conditioning rumble which advanced sound systems may faithfully reproduce. Establishing high performance bass response to 25 Hz is the best compromise to eliminate annoying rumbles and other noise. 16

28 Each part of the audio chain is critical. In terms of establishing clarity the huge challenge is in the mid range. Spanning almost four octaves, given the audio bandwidth approaches 9 octaves, the Mid Band accounts for 45% of the information. Complications abound due to dealing with 60 x 40 wavelengths between 5.5 feet down to 6 inches (1.68 meters to 153mm). Mid Range This has almost impossible impact on either transducer diameter or wave guide mouth size. It is critical to maintain frequency response stability to at least 45 degrees off axis in addition to establishing the lowest levels of distortion. Leader Cinema Systems has achieved remarkable success in wave guide development coupled to recent advances in high performance neodymium magnet structures for precision transducers. The LCS 6040 Mid Range is a medium format wave guide with a Directivity Index (Di) 800 to 2000 Hz of 12.6 db. The resulting off axis performance provides symmetrical frequency response across the 60 Horizontal coverage angle such that the response in the critical band 300 to 2000 Hz is +/- 3dB throughout the coverage angle. In the complex vertical 40 coverage angle, the symmetry tracks with the horizontal deviating by less than 1.2 db. This establishes stable acoustic power output from the device. Lobing errors are eliminated. The benefit apart from superlative sound, establishes an exceptionally stable stereo Left-Right image in a stereo pair, which, when three systems are in operation as in the case of Left-Center-Right Main Screen Channels, the power response across the screen both on and off axis remains stable. Hence, the control of a single sound image, such as Center Channel dialog or effects, remains balanced with two channel (stereo) effects, which may also include the Center Channel. So accurate is the Center Channel dialog, that upon occasion the unusual experience is that the voice appears to emerge in front of the screen on the audience side. We still need to figure that phenomenon out, as strange as it appears. The LCS 6040 is a 140 Lbs / 64 Kgs enclosure. Our design concept was to create a new type of mid range system appropriate for installation in medium sized studios, presentation theaters and post production facilities. This near field to mid field actual performance is in major part a function of the room s acoustical treatment. Simply stated, the more sophisticated the treatment, the further or more distant is the ideal Critical Distance away from the speaker array. The inert mass of this Mid Frequency system is a complex wave guide containing 2 inch / 50.8 mm wall construction containing multiple layers. This decoupling of energy within the structure significantly improves clarity and intelligibility over typical mid range horns and naked dome mid range drivers. The system exhibits no linear or non linear resonance modes that would otherwise color or mask the sound. The dialog and voice quality in music is completely believable. The physical aspects of highly complex enclosure wall design together with optimized mid range transducer utilizing exceptionally powerful neodymium magnet structures provides exceptional transient behavior without cone break up. The advances in smaller magnetic structure over conventional designs provides higher and more intense magnetic field. Hence, the reduction in moving mass of the voice coil and entire voice coil structure are further elements resulting in the astonishing clarity throughout the mid range. 18

29 It requires only some 2 watts to create 113 db SPL at 1 Meter, resulting in peak SPL for cinema. At normal operating levels in cinema (calibrated to 85 db SPL for Dolby 7 ) where average levels may extend to moderately loud passages to 95 to 100 db SPL, only a miniscule watts is required to achieve 98 db SPL. The resulting distortion levels: Second Harmonic 1000 Hz Third Harmonic 1000 Hz High Frequency System 1 LCS 90 x 40 CD High Frequency Section Operating Bandwidth: 1600 to 20,000 Hz Directivity Index (Di) = 11.7 db (Constant Directivity) Coverage Angles: Horizontal 90 Vertical 40 Driver: Neodymium System Sensitivity: 1 watt = 113 db SPL Efficiency: 25% (Twenty Five Percent) Long Term Power Handling: 60 Watts Output: 60 Watts electrical input power = 132 db SPL Output in Acoustic Watts: 19 Acoustic Watts (not electrical amplifier watts) Distortion at 115 db SPL: Less than 00.1% 5000 Hz Due to the shaped power spectrum in high frequencies, in typical operation, SPL to 115 in high frequencies is rarely achieved, although it is entirely possible to acoustically output these levels in large environments. It requires only watts or just over ½ volt ( Ohms) to develop 98 db SPL, resulting in distortion levels below 00.08% at 5000Hz. In a similar discussion to that above concerning the Mid Range Section, the off axis stability in acoustical coverage and power response holds true for almost 3.5 octaves. This may be seen in the Beamwidth Data illustrated on Page 5. Across the High Frequency section, the off axis frequency response is maintained within 3 db out to 16,000Hz across the 90 Horizontal and 40 coverage angle. The stability in the resulting 2 channel Left-Right stereo image and multi-channel power imaging across the screen in a cinema application creates a sound field bordering itself upon a three dimensional representation. With well recorded musical two channel stereo content, the listener is aware of a rock solid center phantom image. Further, the sound field appears to extend beyond the limits of the physical location of either the Left or Right speaker system. This is again due to the stability in the offaxis acoustical power performance which, to state briefly, radiates stable energy to + / - 45 (0 degrees overall) off the center axis. No naked dome tweeter has this capability, hence even exotic and expensive speaker systems developed for the consumer industry is incapable of this level of performance. A review of many HF devices will illustrate the reduction in horizontal coverage beyond 25 to 30 degrees off axis, where the frequency response decreases at varying rates dependent upon frequency. 19

30 Stated another way, when a listener is positioned in front of the Leader LHF(tm) Right Channel for example, the experience is that the sound field commences beyond the Left Channel, passing through the imaginary center, and exits beyond the Right Channel. There is also an uncanny illusion of elevation in the mid and high frequencies on some recordings. The Z axis (front to back) may be experienced on many classical recordings and traditional jazz. As the reader may now be aware, once the dimension of space is created or reproduced from the Main Front channels either in two channel front, three channel front or five channel front the immersive experience now becomes further enhanced with multi-channel surround sound for cinema. With the development of 3D sound such as Dolby ATMOS(tm) and Auro3D, Leader Hollywood Format(tm) front channels further enhance and optimizes the three D sound field.
